Outcome Measures
Primary Outcome Measures
- Progression Free Survival (PFS) Based on Independent Radiologic Central (IRC) Review [Day 28 of Cycle 1, Cycle 2 then every 8 weeks until disease progression or death due to any cause, whichever occurred first (up to 48 months)]
PFS: time from randomization to date of progression of disease (PD) as determined by IRC review as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria or death due to any cause, whichever occurred first. PD: >=20% increase in sum of diameters of target lesions (TLs), referring smallest sum on study, sum must be an absolute increase of >=5 mm, appearance of >=1 new lesions; unequivocal progression of existing non TLs. Overall tumor burden increased sufficiently to merit discontinuation of therapy. In presence of stable disease (did not achieve partial response, complete response or PD) or partial response (>=30% decrease under baseline of sum of diameters of all target measurable lesions, short diameter used in the sum for target nodes, longest diameter used in sum for all other target lesions) in target disease; for new lesions: appearance of any new unequivocal malignant lesion indicated PD.

Criteria for vital signs abnormalities: systolic pulse rate less than (<) 50 beats per minute (bpm) or greater than (>)130 bpm and maximum increase or decrease from baseline in pulse rate of 30 bpm. Systolic blood pressure of maximum increase from baseline (MIB) >=40 millimeters of mercury (mmHg), maximum decrease from baseline (MDB) in systolic blood pressure =<60 mmHg. Diastolic blood pressure of MIB >=20 mmHg and MDB in diastolic blood pressure >40 and =<20 mm Hg. Only categories with at least 1 participant with abnormality are reported in this outcome measure.
- Number of Participants With Clinically Significant Abnormality in Electrocardiogram (ECG) [From baseline up to 28-35 days after last dose of study drug (up to 48 months)]
ECG parameters included corrected QT interval using Bazett's formula (QTcB) and corrected QT interval using Fridericia's formula (QTcF). ECG criteria for abnormality: absolute value 450 - <480 msec, 480 - <500 msec, >=500. The number of participants with potentially clinically significant ECG findings at any visit were reported.
- Number of Participants With Maximum Relative Decrease From Baseline >20% in Left Ventricular Ejection Fraction (LVEF) [From baseline up to 7 days of Cycle 4 (up to 91 days)]
An ejection fraction (EF) was the volumetric fraction of blood ejected from a ventricle of the heart with each heartbeat; it was a measure of the pumping efficiency of the heart. The EF of the left heart, known as the left ventricular ejection fraction, was a measure of the efficiency of pumping into the body's systemic circulation.
- Health Related Quality of Life (HRQOL): Time to Deterioration (TTD) in Pain, Dyspnea, Fatigue or Cough [Baseline until the end of treatment (up to 48 months)]
HRQOL was measured by standardized questionnaires (European Organization for Research and Treatment of Cancer (EORTC)) quality of life questionnaires (OLQ-C30) and its lung cancer module (QLQ-LC13). TTD in pain (chest, arm/shoulder), dyspnea, fatigue or cough was defined as time between baseline and first occurrence of increase in score of 10 points or greater from baseline in any of these 4 symptoms for at least two consecutive cycles. For those who had not shown deterioration, the data was censored at the last date when the participants completed an assessment for pain, dyspnea, fatigue or cough.
- Overall Mean Scores of Euro Quality of Life-5 Dimension Visual Analog Scale (EQ-5D VAS) [From Cycle 1 Day 1 up to 48 months]
The Euro Quality of Life-5 dimension (EQ-5D) is a brief self-administered, validated reliable generic health status instrument. EQ-5D general health status can also be measured by a visual analog scale (EQ-5D VAS). EQ-5D VAS measures the participant's self-rated health status on a scale from 0 (worst imaginable health state) to 100 (best imaginable health state).
- Maximum Observed Plasma Concentration (Cmax) of Dacomitinib and Its Metabolite PF-05199265 [Pre-dose and 2, 4, 6, 8, and 24 hours post-dose on Cycle 2 Day 1 (Day 29)]
